My desktop/NAS/etc are 500 miles away, so I want an external drive to use with my laptop (and maybe PS4). USB powered if that doesn't mean they're awful. It's not for anything vital/anything important is relatively safe through iCloud and Dropbox.

So is there an external drive which is often recommended here? The WD My Passport Portable Hard Drive 4 TB for £100 seems like a decent price, but I know nothing so feel free to tell me I'm an idiot. Anything from £50 - £100 would be palatable.
